Hua Hin to Phitsanulok Road Trip: Best Stops, Drive Time & Tips

The direct route from Hua Hin to Phitsanulok covers roughly 500 kilometers along Route 33 and Route 117, a journey that typically takes 7–8 hours by car. The highway passes through the lower edge of the Phetchabun Mountains, where the landscape shifts from coastal plains to forested hills and river valleys.

This guide covers the essentials: driving time, fuel costs, road quality, and the most worthwhile stops. Use it to plan whether to push through in one day or split the drive with an overnight stop.

Route 33 connects Hua Hin to Saraburi, where you join Route 1 north to Nakhon Sawan, then pick up Route 117 to Phitsanulok. The roads are asphalted and well-marked, with occasional tolls only on the Bangkok ring road if you choose that detour.

Fuel stations are plentiful along the main highways, with a mix of PTT, Bangchak, and Caltex outlets. Expect to pay around 1,500–1,800 baht for gas, depending on your vehicle’s efficiency.

• Driving time: 7-8 hours (without traffic)
• Distance: ~500 km
• Tolls: none on Route 33/117
• Rest areas every 40–60 km

Road quality on the main highways is generally good, but watch for sudden patches of potholes in rural stretches and be cautious of overtaking slow lorries. Speed limits are 90 km/h on highways, and police checkpoints are common, so keep documents ready.

For families, most rest stops have clean toilets and small playgrounds. Many restaurants offer high chairs, and some have air-conditioned rooms. If you’re traveling with pets, note that despite many cafes being pet-friendly, official accommodation policies vary—call ahead.

Fatigue management is critical on a 7–8 hour drive. Plan to stop every 2 hours at designated rest areas like the one at Khao Khor (Km 68 on Route 117) or the service center in Wang Muang. These spots have shops, food courts, and reasonably maintained restrooms.

A specific hidden off-route spot is the Pa Sak Jolasid Dam, located about 30 km east of the route via Route 2150—it offers a scenic reservoir view.

The route crosses several distinct landscapes: the coastal lowlands of Prachuap Khiri Khan, the agricultural plains of Phetchaburi and Saraburi, and the forested foothills of the Phetchabun range. Each offers a different aesthetic, from pineapple plantations to limestone karsts.

The how to find the best stops and hidden gems between cities guide is a useful resource for spotting unmarked viewpoints and local eateries. Off the highway, you’ll find small markets selling fresh produce like sun-dried bananas and handmade woven goods.

For culture, a 90-minute detour from Phitsanulok brings you to Sukhothai Historical Park, a UNESCO World Heritage Site featuring the ruins of 13th-century temples.
